規格失敗與嵌套路線的API

Question

我正在努力添加一個api紅寶石軌道待辦事項列表項目作爲學習練習，我有問題測試使用嵌套路線的一些規格。

我想使用/ lists/1/endpoint時顯示未完成任務的列表，但是當我運行我的規格時，有UrlGenerationErrors和沒有路由匹配。

有關如何解決這個問題的任何想法？在routes.rb中是否有錯誤？

僅供參考，我確實有指標響應/用戶/ 1 /列表和/列表/所以我也可以顯示什麼列表是由用戶和哪些公共清單，在整個應用程序存在擁有。這是什麼讓應用程序混淆？

謝謝！

規格

describe "#show" do 
    ... 

    context "authorized user is the owner of the list" do 
     it "returns all uncompleted items" do 
     params = {list_id: @personal_list.id} 
     get :show, params 

     expect(response.status).to eq(200) 
     #expect(json).to json 
     end 
    end 

    context "authorized user when looking at a nonprivate list" do 
     it "returns all uncompleted items" do 
     params = {list_id: @open_list.id} 
     get :show, params 

     expect(response.status).to eq(200) 
     #expect(json).to json 
     end 
    end 

    context "authorized user when looking at a private list" do 
     it "returns error" do 
     authWithToken(@api.access_token) 
     params = {list_id: @private_list.id} 
     get :show, params 

     expect(response.status).to eq(400) 
     end 
    end 
    end

列表控制器API

def show 
    @list = List.find(params[:id]) 
    if (@list.permissions == "open") || (@list.user_id == @authorized_user) 
     render json: @list.items.completed, each_serializer: ItemSerializer 
    else 
     render json: @list.errors, status: :error 
    end 
    end 

Answer 1

它看起來像公關問題是你正在發送list_id的參數而不是id。

默認軌的路由#show尋找一個：身份證這也是你使用什麼（正確）的控制器。

嘗試重新寫你的測試如下：

describe "#show" do 
... 
    context "authorized user is the owner of the list" do 
    it "returns all uncompleted items" do 
     get :show, :id => @personal_list.id 
    end 

OR 

    context "authorized user is the owner of the list" do 
    it "returns all uncompleted items" do 
     params = {id: @private_list.id} 
     get :show, params 
    end 
... 
end 

另外要確保的是，你使用了正確的頂層描述。因爲這是一個控制器規格，所以需要匹配控制器名稱。即：

describe Api::V1::ListsController do 
    describe 'show' do
